Overview – Jim Malley Many significant accomplishments in
multiple areas PBEE methodology, becomes foundation for
application specific tasks, OpenSEES Non-ductile concrete advances Ground motion work, especially NGA Procedure for quantifying system
performance (ATC-63) Lifelines, bridges and systems analysis
applications Life beyond NSF looks bright!

Perspectives on 10 years of PEER Earthquake Engineering Research
Lloyd Cluff – PG&E Strategy to establish PEER 1995-96 Role of California Seismic Safety Commission Role of Pacific Gas and Electric Company Lifelines component of PEER User needs-driven research agenda Public/Private/Partnerships (PPP) Leveraged funding

Accomplishments and Future Directions
Accomplishments Leveraged funding
PPP (PG&E, Caltrans, CEC, FEMA, BART) 1996 – 2007 ~$12.5 million Implementation of research results
Useful research results that can be implemented Managing earthquake risks
Improve system performance
Future Directions Lifeline interdependencies during earthquakes
Highways and bridges/Power utilities/Water supply System performance
Individual lifelines Lifeline groups

We do not have recorded time histories for the design earthquake in most parts of the western United States.
We need to rely on simulated time histories like those below.

Northridge Earthquake Red tagged buildings occurred in clusters
The Sherman Oaks cluster is not understood
The Santa Monica and West LA cluster is related to the edge of the LA Basin formed by the Santa Monica fault

Earthquake forecast for Japan just before the 2000 Tottori earthquake
The forecast showed high probability for that earthquake (marked by the cross) and the 2004 Niigata Chuuetsu earthquake to the northeast
